An illustrative example fuel cell electrolyte management device includes a first component having a first density and a second component having a second density that is less than the first density. The first component has a first side including a pocket and a second side facing opposite the first side. The second side of the first component includes a first plurality of fluid flow channels. The second component has a porosity configured for storing electrolyte in the second component. The second component fits within the pocket. The second component has a first side received directly against the first side of the first component. The second component has a second side including a second plurality of fluid flow channels.

A method of fabricating a membrane electrode assembly includes the steps of depositing a catalyst ink directly onto a membrane to form a catalyst coated membrane and hot pressing the catalyst coated membrane. The catalyst coated membrane has a catalyst layer that includes a catalyst and an ionomer.

A polymer electrolyte membrane (PEM) fuel cell power plant is cooled evaporatively by a non-circulating pressurized water coolant system. The coolant system utilizes a hydrophobic porous plug for bleeding air from the coolant water while maintaining coolant back pressure in a coolant flow field of the system. Furthermore, there is a first method for identifying appropriate parameters of the hydrophobic porous plug for use with a known particular coolant system; and a second method for determining proper operating conditions for a fuel cell water coolant system which can operate with a hydrophobic porous plug closure having known physical parameters.
